Doodle Science - November 2014

My first two 3D printed design and prints. Much to my amazement I designed these on a simple cad system, then I printed them, if I can do it so can anyone. Now I'm working on a moving robot. And yes you can see the wire on the saucer, but the craft glows in the dark.

Remember STEM is the acronym for Science, Technology, Engineering and Maths too and I have maths shows.

Something to try. Speed of freezing?

Speed of freezing
In identical ice cube trays put cold water in one and hot water in the other. When placed next to each other in the freezer which will freeze first. The answer rather surprisingly is the hot water. There are several theories about why but as yet it is an unknown of the universe.
